If they've been around awhile they've probably got a gray-headed old geezer who can educate you on spring re-arching. It's a pretty complicated process, and doing it right involves annealing, re-shaping, and re-tempering the spring leaves. I've seen some attempts made at re-arching springs done with a hydraulic press and/or anvils and sledge hammers, with less than ideal results. It's possible that the shop might be able to rebuild your springs with parts they've had on hand for decades, assuming that they have been around for that long.
